The vertical or row positions in each merit similar to that used in an electrical punch no sensing of the top row on the card being eifective first and the brushes sensing the other columns being made effective in succession from the top to the bottom brush in the set. The entire card is sensed from left to right. After the sensing of the top or zero horizontal row of index points on the card, the card returns so that the brushes are again at the left hand end of the card, and are made effective to sense the horizontal row marked 1, that is the index points representing 100 to 199. Again the cards are moved and sensed from left to right, this operation continuing until the ten horizontal rows have been detected.

If at any point in the movement of the card over the brushes a corresponding hole in each card is detected, a circuit is closed through all of the brushes. This, through the instrumentality of a relay, causes the sensing operation to be suspended and another circuit to be closed to cause the tabulator to go through an adding and recording cycle. Intermediate contact devices that are positioned along with the cards determine the value of the particular hole sensed and in turn energize emitters moving in synchronism with the tabulator printing devices, thus causing the tabu-' lator to record the identification of the perforation sensed by printing of a record sheet.

In the printing cycle the tabulator also adds a unit to an adding counter each time such agreement is reached. This counter accumulates all the units resulting from such agreement and carries a total representing the number of agreeing The electric circuits are so arranged that the co pletion of the adding and printing cycle on the of the tabulator releases the relay above mentioned and causes the re-initiation of card comparing. This operation continues until the last position on the cards is sensed. At that point, a total from the counter is automatically taken and printed on the same sheet with the list ofidentification numbers and the counter is either reset or not in accordance with the wishes of the operator.

In the ordinary use of the machine the index cards may then be withdrawn and another set inserted for comparison, the new set being either wholly new or comprising possibly one or more records already compared. Thus the comparison of data on an unlimited number of cross index record cards is made possible.

as indicated by line 9-9 in Fig. 5, and showing the construction of the commutator disks and brush holders which are advanced step by step by the card return mechanism. The machine, as shown in Fig. 3, is provided with three card receivers. The number of card v receivers may be increased to compare a larger ,9 number of cards in combination, by merely add- As these card receivers are alike in structure, a description of one applies to the others as well. The card frames 21 are mounted on acommon base 22. when a card 23 is inserted in a frame it rests on a shoulder 24 (Fig. 4) with itsleft, end leading under the sensing roller 25 (Fig. 6) Both ends of the card 23 are engaged by extension brackets 28 nxed to the card shifting escapement rack 27. From the side of the rack 2'1 there protrude two studs.28 which are held in a slot 29 in the frame, thus guiding the sliding movement of the rack.

A spring drum 30 in engagement with rack teeth 31 on the bottom of rack 27 (Fig. 5) tends i at all times to urge the rack to the left. A separate rack and escapement mechanism is provided for each card receiver.

A pair of escapement pawls 32, 33 cooperate with a series of teeth 34 cut in the top of slide rack 27. Enoughteeth are provided to stop the rack and the card it controlsin one hundred different positions, each position presenting one column of index points on the card for sensing. 'Ihe eocapement mechanism is controlled by a 1m magnet '35 (Fig. 6) mounted beneath the card frame 21. The armature 36 of the magnet is secured to a shaft 37 which projects out of the I card frame (Fig. 5) and has secured to its end, an arm 38. A spring 39 normally tends to hold 19;" the armature 36 away from'the magnet 35. The arm'38isconnected byalinkfltoa crank 41 flxed'on a shaft 42 to which is attached a two armed lever 43. The lever is rocked in a counter clockwise direction when magnet 35 is energized; and when so rocked, a pin 44 on one arm'of the lever lifts pawl 33 while a pin 45 on the other arm of the lever lowers the pawl 32 into engage mentwiththeteeth34onrack27,sothatpawl 33 whm lowered by the return movement of lever 43willengasethenextioothtotheright onthe rack. The enlarged opening in pawl 33 into which pin 44 protrudes, allows a return movement of the rack to the right (Fig. 5) a spring 46 attached to pawl 33 yieldingly urging thepawl into cooperation with the rack at all times.

Apairofcontactsflwiredinserieswithan associated magnet 35 are mounted adjacent the magnet as shown in Fig. 8. To one of the contact blades is fixed an insulation block 48 which isinthepathofthe endofanarm 49 fixed to shaft 37. When magnet 35 is energized arm 49 is rocked and acts to open contacts 47, thus breaking the circuit through the magnet 35, deenergiz ing it and allowing shaft 37 toreturn to normal 133 parallel link 61.

vEach spring 52 is adapted for continuous sliding electrical contact with the associated brush holder or block 51 which carries its particular analyzing brush 50. The seriesof brushes 50, of

which there are eleven, are adapted to bear against a metal cylinder or roller 25 mounted on a nonconducting roller54 which is carried by a shaft 55. The brushes 50 are carried by an insulatingbrush holder 56 securedbetween a pair of side plates 57 of a yoke or ball shaped member designated generally by reference numeral 58.

The armature structure 64 is attracted against the tension of a spring 66 when magnet 67 is energized, at which tune the counterclockwise rocking movement of each toggle plate 62 about its pivotal point 63 will be effective to elevate the frame 58 resulting in the contact of the individual analyzing brushes 50 with the contact roll 25..

The brush holder 56 and analyzing brushes 50 extend completely across the card frame, and

Clockwise rotation of gear 79 serves to move racks 27 to the right, back to the initial I card sensin position. A disk 84 secured to the side of gear 78 acts as a driving connection between the clutch 77 and thegear.

Pivoted at 85 to disk 84 is an arm 86 having a clutch tooth 87. The free end of arm 86 is connected to a toggle plate 88 by a link 89, the end of toggle plate 88 distant from its pivot 90 ,being articulated'at 91 to a rod 92. The rod is urged into position by a spring 94 and tits in an aperture in apin 93 rotatably mounted on the disk 84.

For the purpose of effecting the clutching action there is provided a magnet 95 which, when energized, attracts an armature 96 pivoted at 97,

so that an arm98 engaging a pin 99 of arm 86 will rock thexarin and place the tooth 87 in engagement with ratchet wheel 77.

This action will result in moving the cardcarriages so that the cards are brought opposite the initial sensing position. g

At the termination of the counterclockwise movement of gear 78, a tail 100 of plate 88 will strike a projection lol of a. fixed plate 102 to eifect the disengagement of the tooth 87 and ratchet wheel 77 by a reverse action. The operation of the toggle back over dead center willcause the tooth 87 to be retained out of engagement with the teeth of'the ratchet wheel 77. 7

Also secured to the pivot 97 of armature 96 is an arm 105 (Fig. 6) the free end of which is adapted to bear upon an insulating block 106 to open contacts 107 when mag et 95 is energized. Contacts 107 are retained opened by a latching bell crank 108 aiug 109 of which is adapted to (Fig. 5) secured to the latter.

Below contacts 107 are motor control contacts 111 which are latched closed upon an energization of magnet 95 to complete the circuit through motor 72 (see Fig. 7c) and are unlatched in the manner Just described, to stop the motor at the termination of the driving operation.-

When the cardcarriages move from the. last column sensing position to the end of the escape ment movement, two sets of contacts are oper-' pin thus serving, when lowered, to close contacts 114 "and open contacts 115. The functions of these contacts are more fully discussed hereinafter in an explanation of the wiring diagram.

The devices about to be described, serve to render the brushes effective singly and in succession, the brush for the 0" row first, next the .1 row brush, etc. The commutator connections for selecting the brushes are shown,in Fig. 70. There it is noted that each brush 50 is wired to a separate contact segment 116 on the commutator 117 and each set of brushes is wired to a separate commutator ring 118, the wires leading from the brushes being attached to the associated segments which are arranged in order about the section 118. A pivoted contact frame 119 (Fig. 9) in the commutator carries a pair of brushes that close the circuit between a common contact section 120 and each of the segments. The brushes of the three sets are wired in series by connection wires 121 (Fig. 7c) and 122 between each ring 120 and the eleventh brush 50. contacting with contact roller 25. The frame 1191s adapted to be swung step by step about its pivot so that a circuit is established through the contact roller 25, any one of the brushes 50 in the "0" to 9" row, the corresponding segment 116, brushes in frame 119, then through ring 120 and back to the line. The object of this form of construction is to provide means for sensing mly one row of index points on thecardsatatime,andalsotosensethe rowsin succession, starting with the "0" index row. The devices for moving the frames 119 are actuated after the last index point in a row is sensed. The

' card return mechanism already described serves to actuate the card sensing brush selection shift in a'manner about to be described.

Attached to the armature 96, Pig. 5, at the pivot 97isanarm 123 carryinga feedpawl124. The pawl is urged by a spring .125 into cooperation with a ratchet wheel 126. The shaft 127 (Fig. 9) upon which the ratchet 126 is fixed, also carries four frames 119, three of which cooperate with commutators 117 shown in Fig. 7c, and the other eooperates-with a similar commutator 128 shown in Fig. 7b; the purpose of commutator 126 willbe explained further on in the specification.

'Iheframee ll9remaininthis position during the movement of the cards until the last column of index points on the right side of the cards pass the brushes 50. Then, as already explained, magnet is energized to operate the clutch and bring the cards back with the first column of index points to the left under the brushes. The movement of armature 96 carries along arm 123, and pawl 124 rotates ratchet 126 through one step of movement, placing frames 119) with the contact closed between the 1 segments and contact rings 120. The second row the cards are shifted under the brushes 50. The

successive selection of brushes between the card sensing operations continues until the "9 brush or last row sensing circuit is selected, then the circuit through magnet 95 is broken by a disk 129 carried on shaft 127 and provided with an insulating segment 130 engaged by brushes 131 in circuit with the magnet. Thus, by reason of the break in the circuit, the card return mechanism is not operated after the sensing of the last row of indexpoints on the cards. When a new card sensing operation is desired, after the insertion of a new set of cards in the receivers, the start key .132 (Fig. 70) may be operated to close the circuit around brushes 131 and through magnet 95, the armature of which closes contacts 111 energizing motor 72 to effect a card retum movement bringing the new set of cards into the initial sensing position. v

The card shifting, 56 8 8 and return devices having been dwcribed above it is thought advisable at this point in the specification to give a general outline of the operation of the tabulating or 110 printing mechanism before describing the connections between the card handling devices and the tabulator. I

The tabulating mechanism shown in Fig. 1 and fully described in U. B.'Patent No. 1,762,145 is 116 adapted to be driven by the TM motor which has connections for rotating a listing shaft 134 to which is attached a cam 135 for moving an arm 136 attached to the type bar lifting frame 137. Thetypebars 138areliftedwithauniformmo- 120 tion, the notches 139 out on the inner side of the typebarsmovinginsuccessionpastalatching pawl 140 which is adapted to stop the type bar in any one of its ten printing positions. Each of the pawls 140 cooperates with a latch 141 to which I" is attached a callwire 142 secured at the other end to an armature 143 which is swung when an associated printing magnet 144 is energized. Operation of latch 141 releases pawl 140 which then engages a notch 139. After the type bars 138 13) are stopped in their printing positions, the hammers 145 are releasedto strike the type carriers 146 mounted on the type bar, pressing them against the record paper 147 presented in front oftheprintingplatenleii. Threetypebarsarelll provided for identifying the coinciding perforations presented on the analysed cross index cards. The numbers printed'by the type bars wili range from 0 to 999. Another set of type bars is provided for printing a record of the number of 140 times coinciding perforations appeared on the cross index cards. These type bars are adapted to print totals under control of the accumulator for coimting the items. A sample of a prinbd record sheet 147 is shown in Fig. 8. I

The connections between the card sensing mechanism and the tabulating devices comprise a setofthreeemittingdevices 149suchasshown in Pig. 2and a numeral bar contact setup device 162 suchasthat showninl'i gs. land 7b. The 150 device shown in byits connection with shaft 134 in s'ynchronism with the move-- ment of the type bars 138, the frame bcing'shown I I with a contact made between the "9" stud'15l which is the first one sensed as theframe rotates. The frame 150 is adapted to successively engage the studs 151 in the contact ring as the related typebar 138 passes the various printing positions. If a circuit is completed through one of the studs151 the associated printing magnet 144 isenergizedatthepropertimetoholdthetype bar in printing position. The electrical connections between the tabulator controlled contact device 149 and thenumeral contact device 152 under control of the recordcard carriages are shown in Fig. 7b. The mechanical construction of the numeral bar device 152, is shown in Fig.

5, while the wiring of the device is-shown in Fig. 7b. In Fig. 5 it is noted that an insulating block 153 is secured to one of the racks 27 on the carriage controlling the movement of a cross index card. Secured to the top of the insulated block 153 is conducting contact strip 154 reaching across three rows of inserted metal contacts 155, 156

and 157, mounted on an insulation bar 158. Three extending fingers on the contact strip wipe over 1 ,tween the groups.

the contacts. The bar 158 is rigidly held to the stationary frame of the card shifting devices by a pair of brackets 159. The top contact 155 is a continuous strip reaching across the bar 158 horizontally. The second row of contacts 156 include ninety-nine separate contact members, arranged nine in a group with a slight space be- The third bottom row of contacts 157 are ten in number and are arranged with spaces between each other just as the groups of individual contacts in the row above. Each of the fingers on the conducting strip 154 contacts one of the rows of contacts, so that the two lower rows of contacts maintain an electrical connection with the plain rectangular contact 155.

When the cards are brought into the first colanalyzing position the three fingers on the c ucting strip'are brought slightly to the right position,

of the contacts on the insulating bar 158. In this position no contact is made to energize the circuits through the brushes 150 in any one of the emitting positions.

the racks 27 to bring the second column on the cards over the analyzing to bring the fingers on the conducting strip 154 in position to establish a connection between the common conducting contact 155 and the-first contact 156. As shown inFig. 7b this serves to 5 connect a circuit from one side. of the line to a emitter stud 151 which is touched by the-brush on the frame 150 to establish a circuit through the printing magnet 144 just as the associated type bar reaches the 1 position. Thus units order a numeral is printed indicating the position of coinciding perforations. manner described the conducting strip is' drawn horizontally from one numeral setup contact to another as the'ca'rds are analyzed column by column. The wiring connections from the nine contacts 156 the connections noted It is noted from the construction shown in Fig. 7b that when the tenth column on the card is analyzed, the middle finger of the conducting strip .154 rests on an insulated portion 160 of the bar 158 between the two upper groups at contacts 156, and at the same time the left contact finger engages the contact 157 which is connected with the "l" stud in the tens order emitter. The circuits are then conditioned to control the printing of 10.

Inthis way the 100 vertical columns on the record cards are analyzed, each analysis being made simultaneous with the setup of a numeral by contacts made along the bar 158. If coincid ing perforations are analyzed, the sensing devices are disabled while printing takes place. The wiring of the nine contacts 157 to the related nine studs 151 in the tens emitter is shown in Fi 7b.

At the-end of the analysis of the first row of index points, the cards arebrought back to start the sensing of the second row and it is desired to indicate that the analysis includes index points100 to 199, inclusive. In order to indicate-this by printing a numeral in the hundreds order in the tabulator a c mmutator 128 similar to the commutators 117 described hereinbefore is mounted on the shaft 127 (Fig. 9). When the brush frames 119 are shifted from the first to the second row analyzing positions the brush frame 119. associated with the commutator 128 is moved to establish contact between the main line and the stud 151 in the 1 position on the hundreds order emitter 149 in the tabulater. By means of this connection, all numerals printed by reason of sensing coinciding perforations in the second row of index points will be accompanied by a number 1 in the hundreds 1 position on the printed sheet. After the analysis of the second row of index points the ,brush In the above described manner the conducting strip 154 is drawn across the bar 158 ten times to direct numeral printing impulses through the units and tens emitters 149 while the brush holder 119 is stepped around the commutator 128 to properly direct the printing impulses through the V hundreds order emitter 149 during the analysis of one set of record cards.

At the top of the view in Fig. 7w is shown the wiring diagram of the'tabulating machine. Most of the connections shown are standard construction, and are fully described in Patent No. 1,752.- 145, issued June 10, 1930 'to G. F. Daly et al.

These devices for closing shunt circuits about the control key contacts will be described herein l:fter consideration of the card comparing contro The wiring of the card comparing controls is showninl'ig.7c. startingatapointintheoperation with card carriage rack 27 in the ext'reme left hand position (Fig. 5) the projection 112 on the rack contacts the insulated pin 113 to open contacts 115 and close contacts 114. In this position of the card carriage, the three new cardstobecomparedmaybeplacedbetweenthe card shifter projections 26 and the doors 66 closed to hold the cards in position. When the, doors 68 arelatched thethreecontacts 71 (FigsJ and 7c) are closed to condition part of the card comparing circuit. a

In order to initiate the card comparing operation the magnet must be energized to close the clutch between the motor 72 and the card return devices so that the three cards are brought in position with the first column of perforations above the sensing brushes 50. The circuit through magnet 95 rims from line 161, through wire165, magnet 95, contacts 114 now closed, and then either through brushes 131 or contacts 166 to the other side of the line 162. It is recalled thatasanincidenttothesensing ofthelastrow of perforations in the cards previously compared, disk 129 was turned in position to bring the insulated section under the brushes 131. The disk remained in this position while the cards to be sensed were placed in the receivers. Therefore, in order to complete the circuit, the comparison start key 132 is depressed and the contacts 166 closed.

When magnet 95 is energized, not only is the clutch connection made, but the brush holding frames 119 are stepped around in position to sense-the "0" row on the cards, the disk 129 is advanced to complete the circuit through magnet 95 when the start key 132 is released, and contacts 107 (Fig. 6) are opened while contacts 111 are closed. The closing of contacts 111 completes a circuit through the card shift motor 72. The circuit is from line 161, through wire 167, motor 72, wire 168, contacts 111, and wire 169 to line 162.

The opening of contacts 107 breaks the circuit through brush magnets 67 during the card return movement. The brush magnet circuit includes, contacts 115 that are closed except when the card shift frame is in its lastescaped position, contacts 71 normally closed, wire 170, magnets 67 arranged in multiple, wire 171, contacts 107 and wire 169 to line 162. When the cards are properly positioned to the right, contacts 107 and 111 are reversed by the tripping of latch 106 (Fig. 6) thus the card return motor is deenergized and the brush magnets are energized to bring the brushes 50 into sensing position.

The cards are drawn across the sensing brushes 50, column by column, until coinciding perforations are sensed on all the records, then the escapement mechanism is disabled until a tabulating and counting operation is effected after which the card movement is resumed. The electric circuit for controlling the escapement magnets 35 is conducted from the left side of the line 161, through contacts 115, contacts 71, tabulator controlled contacts; 172 normally closed, wire 173, three sets of escapement magnets 35 and circuit breaking contacts 47, each magnet and associated contacts being wired in series, the sets being arranged in multiple in circuit with wire 174, armature 175, contact point 176 and wire 177 to line 162. As before explained, magmused nets 35 are alternately energized and deenergized by the automatic actuation of contacts 47. The escapement circuit is maintained until a card comparing circuit is made through magnet 178,

then armature 175 is swung clear of point 176 breaking the card shifting circuit until magnet 178 is deenergized at the end of the recording operation.

The three record cards are compared at each index point position and when perforations are presented at the same point on all, an electric circuit is made through sensing brushes 50. The circuit runs from line 161 through contacts. 115, 71, and 172, wire 179, extra brush 50 always in contact with roller 25, to. contact roller 25. Here the connections may be interrupted by the record card separating all sensing brushes 50 from roller 25, or a perforation in the card may permit contact between the two, only one brush 50 is effectiveat a time, the selection being brought about by the positioning of frame 119 as explained in connection with Fig. 5. The circuit traced above continues from contact roller 25, through brush 50 to the segment 116, through the brushes on frame 119 to the common ring 120, then to the next card analyzing apparatus through a wire 121 attached to the common contact ring 120 and extra brush 50 on the second roller 25. From the second card sensing apparatus the series connection continues to the third card sensing apparatus by wire 122, then through the third card sensing means, wire 180, magnet 178, wire 181, tabulator controlled contacts 182 and wire 183 to line 162.

Appearance of coinciding perforations at the sensed index points on therecord cards allows completion of the circuit and energization of magnet 178 which is constructed to attract armature 175 and armatures 184 and 185. Movement of armature 174 as explained before, serves to disable the escapement mechanism during tabulating. Shifting of armature 184 establishes a holding circuit through magnet 178; the circuit includes line 161, wire 186, tabulator controlled contacts 187, wire 188, contact point 189,

armature 184,'magnet 178, wire 181, contacts 182, and wire 183 to line 162. The movement of the other armature 185, closes a shunt circuit including wires190, 191 and contact point 192, about the start key contacts 193 (Fig. 7a) in the tabulator.

tabulator start key contacts 193. Late in the tabulating operation contacts 182 are opened momentarily as contacts 172 are closed, thus the escapement magnets 35 may act to bring another set of index points over the brushes 50 for sensing, before the previously sensed coinciding perforations can again act to initiate a tabulating operation.

When the tabulator is operated, the three numeral printing type bars. 138 (Fig.1) are raised in synchronism with the rotation of the three emitter arms 150. From the contact arrangement shown in Figs. 5 and 7b, and through the emitters 149, impulses are sent through the magnets 144 at the proper times to stop the type bars in position to print a. number corre- 'sponding to the coinciding index points found perforated. The wiring through the printing magnets 144 terminates at one end as shown in 1'18. 7a.

There a connection is made from line 161 by wire 194 to the common contact brush 195, thence through contact roller 196, individual brushes 197, and printing magnets 144 wired to plug sockets 198, 199, and 200. In the highest order printing line awire reaches from plug socket 200 to socket 203 in Fig. 7b, a wire 204 connects socket 203 to contact arm 150; the circuit continues through any of the contact studs 151 'onthe emitter to a contact segment 116 on ring 118, then through brush 119 to the common contactring 120, wire 205 and wire 206 to the line 162. Thus the setting of the brush-frame 119 determines the numeral printed in the hundreds order. a

The commutator unit 128 is similar in construction to the ,three brush selecting commutator units 117 shown in Fig. 7c, and it is operated in a similar way by the pawl 124 (Fig. 5).- However, the dreds bank of the printer control, is out ofcontact with the segments 116 on ring 118 at the beginning of a card sensing operation. It remains in this position during the comparing of the first row of index points on the records. Then, when three frames 119 in the commutators 117 are moved to sense the second row, the brush frame in commutator 128 mounted on the shaft 127 (Fig. 5) is shifted to make contact with the "1 segment 116 in readiness to print the hundreds order numeral in any 01 the numbers from to 199. As the other rows on the cards are selected the brush frame 119 is moved in position to direct an impulse through the hundreds order printing magnet. 144 at the proper time.

The circuit through thejtens order printing magnet 144 continues along a plug wirebetween plug socket 199 (Fig. 7a) and socket 202 (Fig. 7b), wire 207 to brush 150, any of the studs 151-, wire 208, contact 157.conducting member 154,

contact bar 155 and wire ,206-to line 162. The

numeral to be printed is determined by whichever one of the contacts 157 is contactedby member 154 during a tabulating operation, and the position of the member in turn coincides with the position of a perforation along arow on the record card, since the card and member 154 are moved together.

The first ten index point positions in a row on the cards sensed do not have acorresponding active contact 157. But as the card continues tomove, from the sensing of the eleventh to the twentieth index point, conductor 154 contacts the 10" contact 15'! (Fig; 7b) In a similar way the other contacts are successively engaged as the cards are shifted along.

The circuit through the units order printing.

magnet 144 is closed by a plug wire from plug socket 198 (Fig. 7a) to socket 201 in Fig. 7b, wire 209, brush 150, any of the studs 151, one or the wires 210, a contact section 156,-conductor 154, contact bar 155 and wire 206 to line 162. The contacts 15 are arranged in groups of nine, each group containing nine sections each of which is connected by wire to one of said studs 151 in the units emitter. Nine outof every ten index point positions in a row on the card are represented by contacts 156. Between the groups of contacts there areinsula'ted spaces 160 upon which-the conductor 154 stands when one of the the third emitter.

brush holder 119 in the hun- 0" index points along .a row is being sensed. Thus between the contacts and spaces all the index points are accounted for and represented on The devices for counting the number of times that coinciding perforations appear on the-record cards, comprise a connection in the tabulating wiring to the well-known form of electric accumulating mechanism shown at the bottom of Fig. 7a. One form ofthis mechanism isillustrated in Patent No. 1,307,740 to C. D. Lake. Each time the tabulator is operated, a unit is added'to the lowest order of the accumulator. The wiring connections reach from plug socket 211 to which counter magnet 212 is wired, through plug wire 213 to socket 214, wire 215, contacts '216 closed at l in the tabulating cycle, and wire 217 to the side of the line 162. Thus an impulse is directed through magnet 212 in time to add a unit to the lowest order accumulator wheel. The regular form of carrying device transfers the count above nine to the higher order accumulator wheels.

The machine disclosed herein andin application Serial No. 582,966 includes a means for printing a total record of the number counted on the 7 index points on the record cards. The total and reset control circuit is shown at the lower end of Fig. 7b. The circuit includes a pair of brushes 221 normally resting on an insulation ring 222 on a disk 223. 127 (Fig. 9) and is rotated one step upon change of rows during the comparing operation, just as disk 129 is rotated. When the ninth or last row is conditioned for comparison a conducting segment 224 on disk 223 is brought around in position to close the circuit. through brushes 221. The circuit is not entirely closed, however, until the space between two contact spots 225 and 226 is bridged. These spots are located at the end of the first and second row of contacts, on the insulator bar 158 (see Fig. 5). When the conducting member 154 passes from the ninety-ninth or last comparing position, it contacts the two spots 225, 226 and closes the reset control circuit. The circuit runs from line 161, wire 227, spot 225, conductor 154, spot 226, wire 228 through brushes 221 and segment 224, relay contacts 229, wire 222, relay magnet 230 (Fig. 7a) and wire 423 to the other side of the line 162. When magnet 230 is energized, associated contacts 231 (Fig. 7a) are operated to close a shunt circuit across the reset key contacts 232. The reset motor RM then operates the usual total printing and resetting 'mechanism, shown in detail in Patent No.

1,762,145 mentioned'hereinbefore.

During the resetting operation relay magnet "233 is energized. Its associated contacts 229 This disk is fastened to the shaft cooperation between key 132 and latch 234 is delayed so that disk 223 may rotate slightly to break the reset cimtrol circuit at the brushes 221 before it is closed at the contacts 229. A complete card comparing operation may then be performed before the reset control is again effective to print a total of the number of agreeing comparisons counted, and reset the counter.

If instead of resetting the counter it is'desired that the number printed remain on the counter applied to a single modification; it will be under stood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
